Abstract: The most suitable way to achieve breeding in the Pebble-Bed HTR is the installment of a symbiotic prebreeder-breeder system. This report presents the parametric research on both the prebreeder and the netbreeder designs. An optimization of its fuel utilization leads to a lifetime-averaged breeding ratio of 1.00 in the breeding variant. This reference design is named "netbreeder". Detailed information is given about the nuclear, thermohydraulic and economic properties of the reference system. Its potential for fuel utilization is outlined in a comparison of its uranium-ore requirement with that of alternative reactor systems: Compared with a typical PWR and with a "conventional" HTR (conversion ratio 0.71) the symbiotic prebreeder-netbreeder system is marked by a distinctly better fuel utilization. In a limited open-end type scenario of nuclear power its cumulative ore requirements are even lower than that of a combination of PWRs and LMFBRs using oxide fuel. In an unlimited scenario this statement holds for a time span of 75 to 80 years.
